note 55978 added to function.chr

I spent hours looking for a function which would take a numeric HTML entity value and output the appropriate UTF-8 bytes. I found this at another site and only had to modify it slightly; so I don't take credit for this. <?php function unichr($dec) { if ($dec < 128) { $utf = chr($dec); } else if ($dec < 2048) { $utf = chr(192 + (($dec - ($dec % 64)) / 64)); $utf .= chr(128 + ($dec % 64)); } else { $utf = chr(224 + (($dec - ($dec % 4096)) / 4096)); $utf .= chr(128 + ((($dec % 4096) - ($dec % 64)) / 64)); $utf .= chr(128 + ($dec % 64)); } return $utf; } ?> So for example: <?php $str = "Chinese: &#20013;&#25991;"; $str = preg_replace("/&#(\d{2,5});/e", "unichr($1);", $str); ?> ---- Manual Page -- http://www.php.net/manual/en/function.chr.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+55978 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+55978&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+55978&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+55978&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+55978&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+55978&report=yes&reason=non-english Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+55978&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+55978&report=yes Search -- http://master.php.net/manage/user-notes.php
